CEILING-COLLAR FOR GAS,

. SPECIFICATION forming part of Letters Patent No. 353,505, datedNovember 30, 1886.

Application filed April 12, 1886. Serial No. 195,564.

To all whom, it may concern.-

Be it known that I. EDwAnn K. ROLLINS, a citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvements inCeiling Collars for Gas, Steam, and other Pipes; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappcrtains to make and use the same.

In the accompanying drawings illustrating my invention, Figure l is aside elevation of my invention applied to a pipe; Fig. 2, a verticalcentral section of Fig. 1, and Fig. 3 a plan view of. Fig. 1. Fig. 4 isa detached perspective view of the springclasp or holding portion ofFigs. 1, 2, and 3. Fig. 5is a perspective view of a modification of myinvention wherein the spring-clasp or holding portion is integral withthat portion thereof which constitutes the ceiling-collar, and Fig. 6 isa vertical central section of the springclasp in Fig. 5 applied to apipe.

The wall or ceiling collars now commonly used may be described asconsisting ofa short metallic pipe between the ends of which is adish-shaped collar similar to the collar portion shown in Figs. 1 and 2,and with a hole through the pipe below the collar in which to fit aset-screw to secure such ceiling-collar in position upon a steam-pipe,the whole being cast of one piece or metal, and with its pipe portionlarge enough to freely slide upon a gas or steam pipe of ordinarydiameter. Such wall or ceiling collars, however, are subject to thefollowing objections, to wit: First, the expansion and contraction ofthe steam-pipe causes the collar to work loose and drop away from theceiling; second, the set'screw invariably draws the ceiling-collar outof'level, so that the collar cannot be set level against the ceiling orplastering, and, third, they are quite expensive.

By my invention all these objections are avoided, and I will nowdescribe it.

In Figs. 1, 2, and 3, A indicates a gas or steam pipe to which myceiling-collar is (No model.)

applied; 13, the ceiling-collar of the form shown, the upper edge ofwhich in the figures is supposed to evenly abut or fit against theplastering or ceiling of a room. spring clasp or holding collar, whichat its base is made with an annular rim or ledge,

d, which forms a support forthe ceiling-collar B to rest upon when inuse, as indicated in Figs. 1 and 2. The springclasp or holding-collar Ois also made with an inner ring port-ion, as e, to encircle the gas orsteam pipe A, as shown, while from a circular portion,f, spaced springclasps or grips F project upwardly, and in practice are made to inclineinwardly with the surface of their ends 9 on vertical lines, which ifprojected less than the diameter of the gas or steam pipe A to causethem to grip such pipe when placed thereon, as shown, and so hold theupper edge, 6, of the ceiling-collar B in even and level juxtapositionwith the ceiling or plastering of a room when the wall or ceiling 8ocollar is in use.

In Figs. 5 and 6 I represent my invention as embodied in a singlehomogeneous piece of metal consisting of the ceiling-collar B, having anannular body extending to the pipe ceiling-collar with its edge 13 inlevel juxtapoo sition with the ceiling when in use.

\Vhat I claim as my invention is 1. The within-described eeiling collarfor gas or other pipes, formed with an upper edge adapted to fit fiushagainst the ceiling, an

annular body extending to the pipe, and internal upwardly-bent springclasps or holders adapted to embrace the pipe, and to be Uisa' In otherwords, 7c.
